To all whom it nui y concern: 1 i

Be it known that I, WILLIS O. C. ELLIS, a

citizen of the United States, residing at Greenfield, in the countyof Fayette and State of Ohio, have invented new and useful Improvements in Nut-Locks for Axle-Spindles, of which the following .is a specification.

This invention relates. to-anutlock' for i axle spindles fonpositiwely maintaining the; 111' (1 wheel on the spin e, and while the invention is particularly adapted to this use, it possesses ;certain features renderin able for use inconne'ction with bo ts.

The invention has forone of its objects to improve and simplify the construction and operation of devices of this character soas to -be comparatively easy and inexpensive to manufacture, thoroughly reliable and efficient in use,'and convenlently applied.

A further object ofthe invention is the provision of a nutlock including a locking member or follower mounted in the spindle of an axle or shank of a bolt as the-case may be, and ada ted to engage in a socket in the nut and re eased from the socket by a special form of wrench when it isdesired to move the nut. u With theseobjects in' v ew and others, as

i ,will appear as the description proceeds, the

invention comprises the various novel featurcs of construction and arrangement of parts which will be more fully described ereinafter and set 'forth with particularity;

- in the claims appended hereto.

In the accom anying drawing, which illustrates oneof t e embodiments of the invention, Figure 1 is'a longitudinal section of an axle spindle and hub portion of a wheel with the lmproved nut lock applied thereto. .40

Fig. 2 is a transverse section on line 2-2,

moved.- Fig. 4 is an end viewof the axle spindle. Fig. 5 is a plan view of the lockreleasingwrencli. F1g. 6;is a longitudinal section thereof.

Similar reference characters are employed to designate corresponding parts throughoutthe several views.

' Referring to the drawing, 1 designates an axle having -a s indle 2 on which rotates a wheel 3 of .usua form. Thefspind'le 2 has a central bore 4extending inwardly from the outer end to a suitable distance and in which is located a longitudinally, movable docking member or bolt 5 which is normally urged outwardly by a helical compres'sreili Spring -berl5 in unlocking tension 11 is forme in the nut.

6 disposed between the inner ends of the look-- ing member 5 and ,bore 4. The locking member is retained in the bore by a key in the form of a countersunk screw 7 arranged in thes indle and extending into a 1011 i tudinal 8 ct 8 in the locking member. T e

.outerf end of the locking member is adapted to engage in a non-circular socket 9 in the interface of the cap-nut 10 that screws on the threaded portion of the axle s indle, the locking pin being non-circular W ere it enters the socket so as to prevent the nut from working loose. In order to hold the mem- (position, a pin-like exon the outer member thatprojects through a central opening 12 A specialform of wrench is required for taking off or screwingon the nut. Preferably,.the wrench, as shown in Figs. 5 and 6, is of that type commonly used for buggiesand has anon-circular opening 13 forengaging around the non-circular portion 14 of the nut.- The shank 15 is cast orotherwise formed with a web 16 that projects across the opening 13 on which is a pm or key. 17 which the locking pin and cause t e atter to be forced inwardly as the wrench is placed on the nut. As long as the wrench is on the is so located as to engage the roiection 11 0f nut, the locking member will be held in unlocking'position, thereb permitting the nut to be removed or place on the s indle, and as soon as the wrench 1s remove and after screwing on the nut, the locking pin will spring outwardly and engage in the socket 9.

From the fore oing description, taken in connection with '51 the advantages of the construction and of the method of operation will be readily-apparent to those skil ed in the art to which the lnventhe principle of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof, I desire to have 'it understood that the apparatus shown is merely illustrative and that such changes may be made when desired, as are within the scopeof the claims.

Having thus described the invention, what Iclaim is:

1. In a nut lock, the combination of a member provided with a bore extending inwardly from one end and with a threaded aperture disposed transversely to the bore 0 accompanying drawings,

and leading into the latter, a longitudinallyelement movable movable locking piece held from rotation in the bore, a spring disposed in the bore and bearing against the inner end of the said 1606, a nut threaded on the member and axle having a longitudinal, central bore exfrom one end, a' locking tending inwardly longitudinally in the bore 'in presence oftwo sss,'1oa

and provided with a longitudiuai slot in one side, a spring in the bore acting on the element, awhe'elon the axle, a nut on the axle central-opening, a pin-like extension on the element passin -.through the opening of the nut and norma y filling the latter, a, removable retaining device secured in the axle and engaging inthe groov'eof the element for removably holding the latter in place, said retainingdevice' being located at such a point as to be retained in position by the Wheel.

In testimony whereof I affix my signature Witnesses. WILLIS' O. C. ELLIS. Witnesses: 4 I x p C. S. ELLIS, W. E; KNEDLER.
